“…Therefore, these parents should be considered as the best lines and tester in breeding program aimed to improve seed and oil yield of safflower. Specific combining ability effects is an important parameter for estimating and selecting superior cross combinations and measure of non-additive gene action which might be exploited through heterosis generally suggested for cross pollinated species such as maize, sunflower and rye (Ortis et al, 2005;Huang et al, 2013;Dehghanpour and Ehdaie, 2013;Goncharenko et al, 2013;Chigeza et al, 2014;Patel and Shrivastava, 2016). Beside of this specific combining ability effects can be used to select homozygous lines that show transgressive segregation for self-pollinated plants like chickpea, rice, alfa alfa, safflower, wheat (Bicer, 2008;Shukla and Pandey, 2008;Al Lawati et al, 2010;Golkar et al, 2011;Istipliler et al, 2015).…”

This research, having F1 hybrids from 6 female lines and 4 male testers, was conducted in order to design to assess the combining ability, to determine the nature and magnitude of gene action, hybrid vigor for yield and related traits and to detect the appropriate crosses for breeding program in safflower. Parents used in the study were developed at the Transitional Zone Agricultural Research Institute (TZARI). In the first year of this research, lines and testers were crossed in all the possible combinations using line x tester mating design. The hybrid population was evaluated in a replicated field trial in Eskisehir, Turkey. According to the results, the specific combining ability (SCA) effects were determined higher than general combining ability effects (GCA) in terms of traits studied. As a result, low ratios of 2 GCA/ 2 SCA, (2 D/ 2 A) 1/2 implied that nonadditive effects controlled the traits studied. Existing non-additive gene action in the population, the selection in the advanced generations like F4 or F5 might be effective for improving the high seed and oil yield safflower genotypes

“…[34][35][36][37] Upon examining the off spring of the populations involved in these studies, it was found that SCA effects can be detected via crossing genetically distinct genotypes and geographically distant population. 36 However, most workers have reported greater relative importance of nonadditive genetic effects than additive genetic effects for grain yield in maize, 23 rice, 38,40 sorghum, [44][45] sunflower, 32 rye, 46 tomato, 50 and linseed. 52 For example, in a study by Dehghanpour & Ehdaie, 14 SCA effects were considered for more than 74% of the sum of squares among the hybrids.…”

In any hybridization program, recognition of the best combination of two (or more) parental genotypes to maximize variance within related breeding populations, and as a result the chance of recognizing superior transgressive segregants in the segregating populations, are the most critical challenge to plant breeders. Since the combining ability was introduced in 1942, it has been widely adopted in plant breeding to compare performances of lines in hybrid combinations. In addition, the ability to predict optimal genotype combinations for different traits based on molecular-based genetic data would greatly enhance the efficiency of plant breeding programmes. This article reviews our current understanding of combining ability in plant breeding as well as recent advances in research in this field. It brings an introduction to combining ability and the concept of general and specific combining ability, methods for estimating combining ability, and QTL mapping of related traits.
